Problems solved by technology

However, the above-mentioned water-in-oil type emulsified cosmetics all exhibit high ultraviolet protection ability by mixing a large amount of zinc oxide, so there are disadvantages in usability such as rough feeling (kishimi) or coating feeling (film feeling)
[0006] In addition, Patent Document 3 is known as a prior art in which a benzophenone-based ultraviolet absorber used in the present invention is mixed, but this is an invention related to photostability and ultraviolet absorbing effect, and does not mention usability

Abstract

The present invention provides a water-in-oil emulsified cosmetic preparation containing (a) to (d) described below, and is characterized by the total content of (a) and (b) being 7-40 mass%. (a) 3.0-30 mass% of isododecane; (b) 1.0-10 mass% of dodecamethylcyclohexasiloxane; (c) 0.1-5.0 mass% of alkyl polyether co-modified silicone with branched siloxane bonds; and (d) 0.1-5 mass% of one or more kinds of UV absorbers selected from 2-hydroxy-4-methoxybenzophenone and diethylamino hydroxybenzoyl hexyl benzoate. The purpose of the present invention is to provide a water-in-oil emulsified cosmetic preparation that has excellent protective effects against UV rays, is smooth, has good elongation, and feels good to use.

Description

technical field [0001] The present invention relates to a water-in-oil type emulsified cosmetic, and more specifically, to a water-in-oil type emulsified cosmetic having a high ultraviolet protection effect, good spreadability, and a smooth feeling in use. Background technique [0002] Among the ultraviolet rays of the sun, the wavelengths of 280-320nm in the mid-wavelength ultraviolet part cause erythema called sunburn on the skin, and in severe cases, cause blisters similar to burns. It is also known that the wavelengths of 320-400nm in the long-wavelength ultraviolet part will darken the skin, and if all the wavelengths are repeatedly applied for a long time, it will accelerate the aging of the skin. [0003] In order to prevent the adverse effects of ultraviolet rays on the skin, people use sunscreen cosmetics mixed with ultraviolet absorbers or ultraviolet protection powders, and it is known that water-in-oil emulsion compositions have good sweat resistance.
